Halo has long been Microsoft’s killer IP, and one of those franchises that acts as an incentive for people to upgrade their existing Xbox console. The series has had its ups and downs over the years, especially with Halo 5 proving to be a major disappointment for anyone who has a stake in the single-player campaign. Halo 6 will hopefully be a return to form, and remind people why Halo has been so highly regarded in the past.
